Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977420, here are decompositions:

7 + 977413 = 977420
13 + 977407 = 977420
61 + 977359 = 977420
97 + 977323 = 977420
151 + 977269 = 977420
163 + 977257 = 977420
181 + 977239 = 977420
211 + 977209 = 977420

Showing the first eight; more decompositions exist.
